Why are you working 60 hours? I know it depends on the companies policy, but 60 hours is a lot for part time. Even part timers at my work place are not suppose to exceed more than 35-40 hours a week.
if it 30 hours a week that considering part-time.. I worked 60 hours a week, madness hours, tiring.. However, if they put you working so many hours, at least make you a full time. I guess anything under 39.5 hours per week companies don't require Medical Insurance.
